Hi, here is my submission for the VLSI placement challenge.
Results:
0.0000 Overlap and avg WL: 0.5224 (for test 1-12)
Runtime: 1800 secs for the 100k cell test (Test 12) and ~40secs for (Test 10).
Also, I had to optimize the evaluation function (
calculate_overlap_metrics) because the original code used an O(N^2) loop that was hanging forever on the 100,000 cell test case. I replaced it with a spatial hash (grid) approach to make it run in O(N) time. The logic remains exactly the same, just faster.
